Augmenting complex and dynamic performance through mindfulness-based cognitive training: An evaluation of training adherence, trait mindfulness, personality and resting-state EEG

Human performance applications of mindfulness-based training have demonstrated its utility in enhancing cognitive functioning. Previous studies have illustrated how these interventions can improve performance on traditional cognitive tests, however, little investigation has explored the extent to which mindfulness-based training can optimise performance in more dynamic and complex contexts. Further, from a neuroscientific perspective, the underlying mechanisms responsible for performance enhancements remain largely undescribed. With this in mind, the following study aimed to investigate how a short-term mindfulness intervention (one week) augments performance on a dynamic and complex task (target motion analyst task; TMA) in young, healthy adults (n = 40, age range = 18-38). Linear mixed effect modelling revealed that increased adherence to the web-based mindfulness-based training regime (ranging from 0-21 sessions) was associated with improved performance in the second testing session of the TMA task, controlling for baseline performance. Analyses of resting-state electroencephalographic (EEG) metrics demonstrated no change across testing sessions. Investigations of additional individual factors demonstrated that enhancements associated with training adherence remained relatively consistent across varying levels of participants' resting-state EEG metrics, personality measures (i.e., trait mindfulness, neuroticism, conscientiousness), self-reported enjoyment and timing of intervention adherence. Our results thus indicate that mindfulness-based cognitive training leads to performance enhancements in distantly related tasks, irrespective of several individual differences. We also revealed nuances in the magnitude of cognitive enhancements contingent on the timing of adherence, regardless of total volume of training. Overall, our findings suggest that mindfulness-based training could be used in a myriad of settings to elicit transferable performance enhancements.

Effectiveness of an online short-term audio-based mindfulness program on negative emotions during the COVID-19 pandemic: Latent growth curve analyses of anxiety and moderated mediation effects of anxiety between mindfulness and negative affect

This pilot study aims to explore the effects and mechanisms of a mindfulness-based intervention on negative emotions in community settings during the COVID-19 pandemic. Participants (N = 100) were randomized into an intervention group (n = 50) and a waitlist control group (n = 50). Participants in the mindfulness group underwent 3 weeks (21 sessions) of an online audio-based mindfulness-based intervention program and completed the online measures four times whereas those in the waitlist control group needed to complete the measures twice. Participants completed measures of the Hospital Anxiety and Depression Scale and Positive and Negative Affect Schedule. The results of the measures of the two groups were compared. Moderated mediation analysis was used to analyze intervention outcomes on negative affect through anxiety. Unconditional quadratic latent growth analysis was used to test the growth trajectories of anxiety. The results showed that this intervention program was effective at improving positive affect and at reducing depression, anxiety, and negative affect. The baseline anxiety moderator was found to be significant, and indirect effects of anxiety post-intervention were found between the mindfulness-based intervention and negative affect. Anxiety levels of participants were not at the same starting point and had similar but non-quadratic growth trajectories. The mindfulness-based intervention program was effective at promoting mental wellbeing and reducing mental problems in community settings in China. Mindfulness practices were beneficial to people with different anxiety levels but had more obvious benefits on anxiety and a negative affect for participants with low anxiety levels. Clinical trial registration: ISRCTN16205138 on 26/02/2021.

Who Benefits Most? Interactions between Personality Traits and Outcomes of Four Incremental Meditation and Yoga Treatments

Mind-Body Medicine (MBM) includes a broad range of interventions with proven preventive and clinical value, such as yoga and meditation. However, people differ in their preferences and response to different MBM treatments and it remains unclear who benefits most from what type of practice. Thus, finding moderators of treatment outcome seems to be a promising approach. This was the aim of the present study. We conducted a single-case multiple-baseline study investigating the outcomes and moderators of four different MBM treatments. Fifty-seven healthy participants with no prior experience were randomly assigned to three baselines (7, 14, and 21 days) and four eight-week treatments: mantra meditation alone, meditation plus physical yoga, meditation plus ethical education and meditation plus yoga and ethical education. We analysed the data using effect size estimation, multiple regression and cluster analyses. High anxiety, high absorption, low spirituality, low openness and younger age were associated with a range of positive outcomes, such as increased wellbeing or decentering and decreased mind wandering. Receiving ethical education consistently improved wellbeing, while engaging in physical yoga reduced mind wandering. In the cluster analysis, we found that participants with a more maladaptive personality structure enhanced their emotion regulation skills more. Consequently, people do differ in their response to MBM interventions and more vulnerable people, or those high in absorption, seem to benefit more. These findings could support the development of custom-tailored MBM interventions and help clinicians to make scientifically sound recommendations for their patients.

Learning Compassion and Meditation: A Mixed-Methods Analysis of the Experience of Novice Meditators

Over the last decade, numerous interventions and techniques that aim to engender, strengthen, and expand compassion have been created, proliferating an evidence base for the benefits of compassion meditation training. However, to date, little research has been conducted to examine individual variation in the learning, beliefs, practices, and subjective experiences of compassion meditation. This mixed-method study examines changes in novice meditators' knowledge and contemplative experiences before, during, and after taking an intensive course in CBCT® (Cognitively-Based Compassion Training), a contemplative intervention that is increasingly used for both inter- and intrapersonal flourishing. The participants in this study (n = 40) were Christian healthcare chaplains completing a 1-year residency in Clinical Pastoral Education (CPE) who learned CBCT as part of their professional chaplaincy training curriculum. Prior to and upon completion of training, we surveyed participants to assess their beliefs about the malleability of compassion, types of engagement in compassion meditation, and perceptions of the impact of taking CBCT. We also conducted in-depth interviews with a subset of participants to gain a qualitative understanding of their subjective experiences of learning and practicing compassion meditation, a key component of CBCT. We found that participants reported increases in the extent to which they believed compassion to be malleable after studying CBCT. We also found high levels of variability of individual ways of practicing and considered the implications of this for the study of contemplative learning processes. This multi-methodological approach yielded novel insights into how compassion practice and compassion-related outcomes interrelate, insights that can inform the basic scientific understanding of the experience of learning and enacting compassion meditation as a means of strengthening compassion itself.

Towards an Individual Differences Perspective in Mindfulness Training Research: Theoretical and Empirical Considerations

A growing body of research indicates that mindfulness training can have beneficial effects on critical aspects of psychological well-being, cognitive function, and brain health. Although these benefits have been generalized to the population level, individual variability in observed effects of mindfulness training has not been systematically investigated. Research on other similar forms of psychological intervention demonstrates that individual differences are prominent in terms of intervention responsiveness and outcomes. Furthermore, individual characteristics such as personality traits have been shown to play a crucial role in influencing the effects of intervention. In light of these lines of evidence, we review representative work on individual differences in mindfulness training and advocate for an individual difference perspective in mindfulness training research. We discuss relevant empirical evidence of individual differences potentially influencing behavioral outcomes of mindfulness training, focusing on both cognitive function and psychological well-being. Finally, theoretical considerations and potentially fruitful research strategies and directions for studying individual differences in mindfulness training are discussed, including those involving cognitive neuroscience methods.

Patients' Experiences and Perceptions of a Consultative Model Integrative Medicine Clinic: A Qualitative Study

Objective: A common theme in integrative medicine (IM) is patient-centered partnering in care between patients and providers. Despite the stated ideals, few studies have assessed patients' perspectives on their actual experience in the context of a specific care model. The purpose of the present study was to retrospectively explore and compare experiences of cancer and noncancer patients under care in a consultative IM outpatient teaching clinic in the south-western United States. Design: Qualitative study using inductive content analysis of focus group interview transcripts (2 groups of adult patients with cancers of various types and 1 group of chronically ill noncancer patients with mixed diagnoses). Method: Participants were recruited by random selection from a pool of eligible patients. Groups were conducted with patients who had completed their initial conventional cancer treatment and were at least 6 months postconsultation with an IM clinic physician. Transcripts of the audiotaped focus groups were analyzed. Results: Cancer patients (n = 15) and noncancer patients (n = 6) (mean age, 60 years; 77% women) expressed overall satisfaction with IM, emphasizing (1) expansion of treatment options with lower perceived toxicity than conventional therapies, (2) positive experiences of the IM physician as caring and taking time to listen, and (3) improved self-care skills and sense of empowerment. Cancer patients noted positive relationships with their conventional MDs more than did noncancer patients, although both groups appreciated the IM physicians' communication styles. Conclusion: Patients experience a consultative integrative clinic model overall as favorable. The impact on outcomes, costs, and long-term quality of life requires additional study.

Key issues in clinical and epidemiological research in complementary and alternative medicine--a systematic literature review

BACKGROUND

In the last 2 decades there has been a large increase in publications on complementary and alternative medicine (CAM). However, CAM research methodology was heterogeneous and often of low quality. The aim of this systematic review was to investigate scientific publications with regards to general issues, concepts and strategies. We also looked at research priorities and methods employed to evaluate the clinical and epidemiological research of CAM in the past to identify the basis for consensus-based research strategies.

METHODS

We performed a systematic literature search for papers published between 1990 and 2010 in 7 electronic databases (Medline, Web of Science, PsychArticles, PsycInfo, CINAHL, EMBASE and Cochrane Library) on December 16 and 17, 2010. In addition, experts were asked to nominate relevant papers. Inclusion criteria were publications dealing with research methodology, priorities or complexities in the scientific evaluation of CAM. All references were assessed in a multistage process to identify relevant papers.

RESULTS

From the 3,279 references derived from the search and 98 references contributed by CAM experts, 170 papers fulfilled the criteria and were included in the analysis. The following key issues were identified: difficulties in past CAM research (e.g., randomisation, blinding), utility of quantitative and qualitative research methods in CAM, priority setting in CAM research and specific issues regarding various CAM modalities.

CONCLUSIONS

Most authors vote for the use of commonly accepted research methods to evaluate CAM. There was broad consensus that a mixed methods approach is the most suitable for gathering conclusive knowledge about CAM.

Extension trial of qigong for fibromyalgia: a quantitative and qualitative study

This extension trial is an open-label observational trial of 20 subjects with fibromyalgia who undertook level 2 Chaoyi Fanhuan Qigong (CFQ) training following an earlier controlled trial of level 1 CFQ. Subjects practiced 60 min/day for 8 weeks and continued some daily practice for 6 months. Quantitative measures, assessed at baseline, 8 weeks, 4 and 6 months, were of pain, impact, sleep, physical and mental functions, and practice time. Qualitative comments also were recorded. Compared to baselines, CFQ practice led to significant improvements in pain, impact, sleep, and physical function in the 13 subjects (65%) who completed the trial; changes were present at 8 weeks and were maintained for the 6-month trial duration. A highly motivated subgroup of N = 5, who practiced the most, had the best outcomes in terms of end symptomology, and qualitative comments indicated health benefits in other domains as well. Qualitative comments by the remaining N = 8 trial completers and N = 7 withdrawals indicate different experiences with the practice. This extension trial indicates that diligent CFQ practice over time produces significant health gains in fibromyalgia in a subset of individuals. Future studies will need to address factors that might predispose to favourable outcomes.

Decontextualized versus lived worlds: critical thoughts on the intersection of evidence, lifeworld, and values

BACKGROUND

Numerous studies and trials are conducted under the evidence-based complementary and alternative medicine (EBCAM) paradigm. Some individuals view the results generated by this approach as symbolic evidential proof of complementary medicine, and as representative of practice. Such evaluations are made even though the ability to capture and reflect clinical reality by the methods used is questioned. The effect of this type of research on complementary medicine researchers and practitioners has received minimal consideration, and this article explores this subject by critically reviewing the literature and theorizing the effects on the lifeworld and values of those embodied by EBCAM.

METHODS

This review accesses the discourse of various disciplines involved with, and commenting on, complementary medicine research. Collected literature is collated within specified limits, subjected to argumentation analysis, and synthesized within a critical theory methodology. Emergent themes are examined, and the effects of EBCAM on holistic researcher and practitioner lifeworld and values are theorized via the colonization framework of critical social theorist Jürgen Habermas.

RESULTS

The use of an evidence-based medicine research model to investigate complementary medicine practice is not well regarded by those who critically examine its use. Within a critical theory framework, the generation and application of research resulting from EBCAM is viewed as a philosophically incongruent process arising from a dominative discourse that can colonize lifeworld. This can result in a variety of pathological symptoms that may have a detrimental effect.

CONCLUSIONS

The application of EBCAM has the theoretical potential to damage complementary medicine culture, profession, and practice. Its ongoing use requires thought, attention, and careful revision, taking into account the lifeworld and values of researchers and practitioners. If this inclusive view can occur, knowledge generation with relevance to the whole of the professions could proceed.

Geffen Faculty Highlight Concerns Linking CAIM and Conventional Researchers at UCLA Symposium

David Geffen School of Medicine faculty, representing a wide range of disciplines, engaged speakers nationally known for their expertise on complementary, alternative and integrative medicine (CAIM) and its investigation at a January, 2008 symposium on the campus of the University of California, Los Angeles. The forum was created to educate the UCLA Institutional Review Board (IRB), and lively participation by School of Medicine faculty helped bring IRB members up to speed on controversies surrounding CAIM research. The symposium demonstrated that academics who are neither proponents nor detractors of CAIM can facilitate cross talk between opposing camps, elucidating questions important to its evaluation by those charged with protecting research subjects. It also brought attention to the universality of quandaries facing CAIM investigators and to the ingenuity with which they have addressed many of them.

Reconsidering the placebo response from a broad anthropological perspective

This paper considers how the full range of human experience may catalyze a placebo response. The placebo effect has been characterized as something to control in clinical research, something to cultivate in clinical practice and something present in all healing encounters. We examine domains in which the term 'placebo' is used in discourse: clinical research, clinical practice, media representations of treatment efficacy and lay interpretations of placebo--an underresearched topic. We briefly review major theoretical frameworks proposed to explain the placebo effect: classical conditioning, expectancy, the therapeutic relationship and sociocultural 'meaning.' As a corrective to what we see as an overemphasis on conscious cognitive approaches to understanding placebo, we reorient the discussion to argue that direct embodied experience may take precedence over meaning-making in the healing encounter. As an example, we examine the neurobiology of rehearsing or visualizing wellness as a mode of directly (performatively) producing an outcome often dismissed as a 'placebo response.' Given body/mind/emotional resonance, we suggest that the placebo response is an evolutionarily adaptive trait and part of healing mechanisms operating across many levels--from genetic and cellular to social and cultural.

The process of whole person healing: "unstuckness" and beyond

OBJECTIVE

The purpose of the present study was to fully explore the descriptions of patients' experiences of change after receipt of whole systems of complementary and alternative medicine (CAM) treatment. The aim was to develop an understanding of "unstuckness," including characterization of states, processes, and modifying factors.

DESIGN

This was a secondary descriptive qualitative analysis, using techniques borrowed from phenomenology and grounded theory.

SETTING/LOCATION

Three existent datasets collected at two different universities in the United States and Canada were used in the secondary analysis.

PARTICIPANTS

Patients with chronic illnesses (including cancer and multiple nonmalignant conditions) who were treated with different packages of care were interviewed for the primary three studies (n = 76 with over 150 interview sessions). Complete data sets from these participants were used in this secondary analysis. OUTCOME MEASURES/DATA COLLECTION TECHNIQUES: Original transcripts were coded asking specific research questions about the experience of change subsequent to whole systems treatments.

RESULTS

Data clearly indicated experiential differences between stuckness, unsticking, and unstuckness. Descriptors and characteristics of each state were identified, as was an initial grounded theory of change or transformation that occurs as an outcome of whole medical systems of CAM.

CONCLUSIONS

The results provide preliminary conceptualizations and descriptions of the impact that CAM whole systems interventions may have on the individual' s life courses. This constitutes a first step in the identification, measurement, and evaluation of whole systems outcomes in a clinical setting. The emerging conceptualization of the process from stuckness to transformation may also provide a link between clinical research and systems science theory.

Adjunctive care with nutritional, herbal, and homeopathic complementary and alternative medicine modalities in stroke treatment and rehabilitation

This article presents an overview of nutritional, herbal, and homeopathic treatment options from complementary and alternative medicine (CAM) as adjuncts in stroke prevention, treatment, and rehabilitation. Despite many promising leads, the evidence does not favor recommendation of most of these treatments from a public health policy perspective. However, simple preventive interventions such as use of a high-quality multivitamin/multimineral supplement in patients with undernutrition may improve outcomes with minimal long-term risk. Natural agents such as the antioxidant alphalipoic acid, certain traditional Asian herbal mixtures, and some homeopathically prepared remedies show promise for reducing infarct size and associated impairments. A number of nutrients and herbs may assist in treatment of stroke-related complications such as pressure sores, urinary tract infections, and pneumonia. Individualized homeopathy may even play a helpful adjunctive role in treatment of sepsis. However, a great deal of systematic research effort lies ahead before most of the options discussed would meet mainstream medical standards for introduction into routine treatment regimens.

Potential synergism between hypnosis and acupuncture—is the whole more than the sum of its parts?

Both hypnosis and acupuncture have gained credibility over the years in their effectiveness for treating various health conditions. Currently, each of these treatments is administered in distinct settings and separate times. That is, even if patients receive both treatments as part of a multidimensional therapeutic program, they would typically receive them separately rather than simultaneously at the same session. This separation however might be undesirable since, at least theoretically, hypnosis and acupuncture could potentially augment each other if administered concomitantly. In this article we outline the rationale for this hypothesis and discuss the potential ramifications of its implementation.

Is complementary and alternative medicine (CAM) cost-effective? A systematic review

BACKGROUND

Out-of-pocket expenditures of over 34 billion dollars per year in the US are an apparent testament to a widely held belief that complementary and alternative medicine (CAM) therapies have benefits that outweigh their costs. However, regardless of public opinion, there is often little more than anecdotal evidence on the health and economic implications of CAM therapies. The objectives of this study are to present an overview of economic evaluation and to expand upon a previous review to examine the current scope and quality of CAM economic evaluations.

METHODS

The data sources used were Medline, AMED, Alt-HealthWatch, and the Complementary and Alternative Medicine Citation Index; January 1999 to October 2004. Papers that reported original data on specific CAM therapies from any form of standard economic analysis were included. Full economic evaluations were subjected to two types of quality review. The first was a 35-item checklist for reporting quality, and the second was a set of four criteria for study quality (randomization, prospective collection of economic data, comparison to usual care, and no blinding).

RESULTS

A total of 56 economic evaluations (39 full evaluations) of CAM were found covering a range of therapies applied to a variety of conditions. The reporting quality of the full evaluations was poor for certain items, but was comparable to the quality found by systematic reviews of economic evaluations in conventional medicine. Regarding study quality, 14 (36%) studies were found to meet all four criteria. These exemplary studies indicate CAM therapies that may be considered cost-effective compared to usual care for various conditions: acupuncture for migraine, manual therapy for neck pain, spa therapy for Parkinson's, self-administered stress management for cancer patients undergoing chemotherapy, pre- and post-operative oral nutritional supplementation for lower gastrointestinal tract surgery, biofeedback for patients with "functional" disorders (eg, irritable bowel syndrome), and guided imagery, relaxation therapy, and potassium-rich diet for cardiac patients.

CONCLUSION

Whereas the number and quality of economic evaluations of CAM have increased in recent years and more CAM therapies have been shown to be of good value, the majority of CAM therapies still remain to be evaluated.
